Intel Core Ultra X7 368H vs Intel Core Ultra X9 378H: Comparison
Core Ultra X7 368H vs Core Ultra X9 378H efficiency cores compared
These two are close on paper, and efficiency cores is the only measure that separates them at all: Core Ultra X7 368H 8 against Core Ultra X9 378H 12. There is a split on memory type as well, LPDDR5x on the Core Ultra X7 368H versus LPDDR5x up to 9600 MT/s on the Core Ultra X9 378H.
Core Ultra X7 368H vs Core Ultra X9 378H: which one fits your build
Take the Core Ultra X7 368H for thin laptops that lean on the 12-core Intel Arc B390 iGPU instead of a discrete graphics chip. The same goes for buyers who want local AI features backed by the 50 TOPS NPU 5 in a 25 W laptop part. It is not the one for desktop builders, since this is a laptop-only FCBGA2540 package with no socket. Buy the Core Ultra X9 378H for premium thin laptops for creators and students in demanding courses and gaming and creative work on integrated Arc B390 graphics, though it is not the pick for budget buyers who mainly browse and use office apps and high-refresh AAA gaming, where a dedicated GPU is still faster. It is equally the pick for copilot+ PC and on-device AI features with a 50 TOPS NPU.
Where the two are identical
Everything else lines up. Total cores, performance cores, total threads, p-core boost clock and p-core base clock read the same on both, so those are not worth weighing. They match on 11 further specifications as well.
Do the Core Ultra X7 368H and Core Ultra X9 378H differ on product line?
Yes. Product Line reads Core Ultra X7 on the Core Ultra X7 368H versus Core Ultra X9 on the Core Ultra X9 378H.
Is the E-Core Base Clock the same on the Core Ultra X7 368H and Core Ultra X9 378H?
It is. Both are listed at 1.6 GHz, so it is not a reason to pick one over the other.
